Sumo iPod Nano Black with White Stripe Wristlet Case. I used this case with the 2nd Generation and do not know what other versions this case would work with.

Features a molded eva foam for protection, which is covered with real leather. The front cover opens to reveal the screen and click-wheel for when the nano is in use, and the bottom includes one large hole through which you can access both the Dock Connector and the headphone port. When closed, the cover attaches via hook and loop. A removable wrist strap is also included. The case is only a few millimeters taller and wider than the nano itself, but it does have significantly more depth than a plain nano does.

In 2006, this retailed for $34.99
